Specification of Letters Patent.

Patented Oct; 24:, 1911.

Application filed October 26, 1910. Serial No. 589,284.

T0 all whom L25 may concem:

Be it known that I, ROBERT A. LYONS, a subject of the King of GreatBritain, and a resident of the city of London, in the county ofMiddlesex, in the Province of Ontario, Canada, have invented a new anduseful Pump-Valve, of Which the follovving is a specication.

This invention relates to a device for opening and closing a passage tocontrol the supply of liquids or such like material, the object being tolessen the amount of rulober or any other like composition used in apump valve or the like; and it consists of the improved construction andnovel combination of parts of the same as Will be hercinafter firstfullv set forth and described and then pointed out in the claim,reference being had to the accompanying draw ings forming part of thisspecification, wherein:

Figure 1 is a top or plan view of a pump valve embodying my invention.Fig. 2 is a side view of same. Fig. 3 is a central cross sectional viewin perspective of Fig. 1.

Referring to the drawings in detail, 1 denotes a circular disk providedwith a centrally-disposed opening 2 and having its upper face formedvvith an annular fiange 3 which surrounds the opening 2.

The lower face of the disk 1 has depending therefrom an annularextension a, the inner face of which forms a continuation of the Wall ofthe opening 2. The lower end of the annular extension a is provided witha laterally-extending annular fiange c which in connection with thelower face of the disk 1 provides a pocket Depending from the disk 1 isan annular rim a having its outer face flush with the edge of thedisk 1. The rim a at its lovver end is formed with an inwardly-extendingannular flange -b Which in connection with the lower face of the disk 1provides a pocket b. The function of the pockets c and b Will bepresently referred to. The extension a and rim a are integral vvith thedisk 1.

The reference character 4 denotes the body-portion of the valve andwhich is formed of any suitable composition preferably rubber, and isprovided with a neck -f and projections d and c. The bocly-portion 1 isprovided with a centrally-disposed opening 2, the wall of which forme acontinuation of the inner face of the extension -a and the wall of theopening 2. hen the body-portion is secured in positon, it is flush vviththe outer face of the rim a, the neck abuts against the edges of thefianges c and -d and the projections e and d extend into the pockets 6and b, the pocket portion snugly fitting against the lower face of theflanges 0 and d, the opposing edges of the flanges c, d, the outer facesof the flanges c, (l, against the extension a and rim a and also againstthe lower face of the disk 1. This firmly and rigidly looks thebody-portion 4: in position.

The valve rod, not shown, is inserted and secured in the opening, 2, andthe pump valve formed of the metal portion 1 and the rubber portion 1 isinserted in a cylinder, net shown.

By setting up a valve in the manner as stated, the amount of rubber orother composition 1 used in this valve is thereby lessened thus making apump valve which Will be simple, strong, durable and cheap inconstruction and efiicient in practioal use.

Having thus described 1ny invention, I claim;

A pump valve comprising a disk having a centrally-disposed opening and avertically-extending fiange surrounding said opening, an annularextension depending from said disk and having its inner face forming acontinuation of the wall of said opening, a rim depending from the lowerface of the disk and having its outer face forming a continuation of theedge of the disk, said extension provided vvith a laterally-extendingannular fiange, said rim formed vvith a laterally-extending annularfiange, said flanges opposing each other and in connection with saiddisks providing a pair of pockets, a bodvportion including a neck and apair of projections, said bodyportion having a centrally-disposedopening with the Wall thereof forming a continua- In testmony whereof, Ihave signed in ton of the inner face 01: said extension, said thepresence of the two undersigned witbody-porton being flush wth the outerface nesses:

of sad rim, the neck of said body-portion ROBERT A. LYONS. abuttingagainst the edges of said fianges Witnesses:

and the projections of said body-porton P. J. EDMUNDS,

being snugly secured in said pocket. S. HARDY.
